APPARATUS FOR IMMERSING TINNED ARTICLES IN GREASE.

SPECIFICATION forming part of Letters Patent No. 433,300, dated July 29, 1890.

Application led March 2l, 1890.

To all whom it may concern.-

Be it known that I, JOSEPH MONTO, of Chel sea, in the count-y of Suffolk and State of Massachusetts, have invented certain new 5 and useful Improvements in Apparatus for Immersing Tinned Articles in the Grease-Pot, of which the following is a specification.

This invention has for its object to provide a simple and effective apparatus whereby a series of holders or carriers for tinned articles located over a grease-pot may be raised and lowered by power automatically stopped both when immersed in and when raised from the bath, and to provide such an arrangement of mechanism as will enable the operator to start each carrier on its downward movement and cause each carrier in movin g downwardly to start the upward motion of another carrier, so that the operation will be automatic, excepting as to starting the carriers on their descent into the pot.

To these ends the invention consists in the improvements which I will now proceed to describe and claim.

In the accompanying drawings, forming a part f this speciiicaticmFigure l represents a top plan view of an apparatus embodying .my invention. Fig. 2 represents a section on line A A, Fig. l. Fig. 3 represents a section on line B B, Fig. l. Fig. 4 represents a section on line C C, Fig. Figs. 5 and 6 represent views of one of the carrier-operating cranks. Fig. 7 is a front elevation of one of the pan holders or carriers.

The same letters of reference indicate the same parts in all the figures.

In the drawings, s S2 S3 represent a series of horizontal parallel shafts journaled in bearings on a suitable supporting-frame- Each shaft is provided at one end with a crank-arm a, and to said crank-arms are connected, by means of connecting-rods l), a series of holders c for the pans d or other articles to be immersed in the grease-pot e, the latter being located under the cranks ct. Each holder is composed of a yoke or frame l0, connected by the rod l) to the crank a, and a pairof arms l2 lf2,pivoted at I3 to said frame, and provided with notches to receive the 5o edges of one or more of the articles d. The

Serial No. 344,747. (No model.)

frame 10 has a sleeve li affixed to it, said sleeve being fitted to slide on a fixed vertical guide-rod g. Each carrier-operating shaft is rotated by means presently described, audits rotation causes its crank a to alternately depress and raise the holder c, thus immersing the articles CZ in and then withdrawing themr from the grease-pot. To each pair of arms 12 is attached a bent rod l5, that extends upwardly between two guides 16 and I6. The form of 6o the rod 15 is such that as the holder rises and falls it will be given a tipping motion, as described in my patent,No. 372,555, dated November l, 1887. Each crank thas a longitudinal slot or guide 1S, which receives a screw 19 and 65 a nut 20, engaged with said screw within the slot. The pivot or wrist pin 2l, that connects the connecting-rod h to the crank a, is formed on said nut, and is therefore capable of adjustment by the rotation of the screw 19 to 7o vary the extent of the upward and downward movement of the carrier.

Each of the above-named shafts has a wormwheel 71., and said Worm-wheels mesh with worms t' on counter-shafts t, t2, and t3, eXtend- 7 5 ing at right angles to the shafts s s2 s3. Each of said counter-shafts is provided with two loose pulleys 1J p', which are rotated in opposite directions by suitable connections with a diivingshaft. Between said pulleys 8o are sliding clutches j, each adapted both to slide lengthwise on and to rotate with the shaft on which it is placed. Each clutch is adapted to enga-ge a corresponding clutch on each pulley-that is to say, when the clutch is moved into contact with one pulley itengages that pulley with the shaft that supports it and causes the shaft to rotate with the engaged pulley, and when the same clutch is moved into contact with the other pulley it 9o engages the latter with the shaft and disengages the other pulley-hence, each of the counter-shafts is adapted to be rotated in one direction by one pulley and in the opposite direction by the other pulley. The construction of the clutches on the pulleys and of the sliding clutches j may be the same as that described in my patent, No. 372,555, above referred to.

r r2 r3 represent longitudinallymovable roo rods, which are adapted to slide in bearings on the supporting-frame, each having an arm m, which is engaged with a clutch j, as shown in Fig. l, said rods being adapted to move the clutches, so as to engage each clutch with either of the pulleys on the shaft which supportsit. To enable the operator to move the clutch-rodslengthwise I provide pivoted levers o 0 0, there being one lever for each rod, each lever being pivoted to a fixed support and engaged at one end with collars affixed to the accompanyin g clutch-rod.

Each clutch-rod is provided with two collars or projections 2 4, Fig. 3,one located over one carrier-operating shaft and the other over another of said shafts. Each carrier-operating shaft is provided with two arms 3 and 5. The

l arm 3 is of the double form shown in Fig. 3, and arranged to engage a collar 2 on one of the clutch-rods, and thereby move said rod first in one direction and then in the opposite direction for the purpose of disengaging the clutch connected with said rod outof engagement with first one and then the other of the twopulleys with which said clutch co-operates, as hereinafter described, the arm 3 being arranged to leave the corresponding clutch in p the inoperative position shown in Figs. 2 and 3.

The arm 5 is arranged to engagea collar 4 on one of the clutch-rods, and thereby move said rod in the direction required to throw the clutch thereto connected into engagement with the pulley p on the corresponding counter-shaft, and thus cause the rotation of the carrier-operating shaft connected with said countershaft and the automa/tic upward movement of the carrier thereon, as hereinafter described. The arm 5 has a yielding terminal ornose 5 which is pressed outwardly by a spring 8, Fig. 4, into position to bear on the collar 4. A fixed arm or detent 6 is arranged near each arm 5 to press said terminal 5 inwardly, as shown in dotted lines in Fig. 3, when the clutch rod has been moved far enough in the direction indicated by the arrow in said figure. Y Y

The method of operation of the machine is as follows: When the machine is in the condition shown in Fig. l, the carrier connected with the shaft s is raised, and the carriers connected with the other shafts s2 and s3 are depressed, and the articles held thereby are immersed in the bath, the clutches of the counter-shafts which transmit motion to said shafts being all out of connection with the pulleys on said counter-shafts. After the elevated carrier has been charged with a fresh load of pans or other articles the operator, by moving the rod 7" that operates the clutch on the counter-shaft i2, throws said clutch into engagement with the pulley p on that shaft, thus causing the latter to transmit motion to the shaft s in such direction as to cause thedescent of the carrier thereon into the bath, the direction being as indicated by the arrowT a in Fig. l. Vhen the said carrier has nearly reached the lowest point in its movement, the rotation of the shaft s brings the arm 5 thereon into contact with the collar 4 on the clutch-operating rod r2 and causes said rod to move the clutch j engaged therewith into engagement with the pulley p of the counter-shaft t2, which is thereby rotated and caused to rotate the shaft s2, thus causing the ascent of the carrier on the last-named shaft. During the latter part of the downward movement of the carrier on the shaft s and just as the said carrier is reachingits lowest point the arm 3 Von said shaft s strikes the collar 2 on the rod r and moves the clutch connected with said rod out of engagement with the pulley p on the counter-shaft t', leaving said clutch inoperative between the two pulleys. The carrier on the shaft s is therefore stopped when immersed in the bath. The shaft s is now at rest, and the shaft s2 is rotating in the direction indicated by the arrow h and raising the carrier on the shaft s2. Just before said carrier reaches its highest point the arm 3 on the shaft s2 strikes the arm 2 on the rod r2 and moves the clutch connected therewith out of engagement with the pulley p on the counter-shaft t2, leaving said clutch in its inoperative position, and thus stopping the shaft s2 when its carrier is fully raised. The articles are now removed from said raised carrier, and the same is refilled and started on its downward motion into the grease-pot by the operator, who for this purpose moves the rod r2 in the direction required to engage the clutch j on the counter-shaft t2 with the pulleyp on said shaft, the shaft s2 being now rotated in the direction indicated by the dotted arrow c so that the arm 5 on said shaft strikes the collar t on the clutch-rod r3 and moves said rod in the direction required to throw the clutch on the counter-shaft t3 into engagement with the pulley p on said shaft, thus causing said pulley, through the counter-shaft t3, to rotate the shaft s3 in the direction indicated by the arrow d and raise the immersed carrier on said shaft. Just after'this and when the carrier on the shaft S2has reached its lowest point the rotation of said shaft s2 is stopped by the contact of its arm 3 on the collar 2 of the rod r2, said contact moving said rod and IOO IIO

the clutch j thereto connected so that the clutch becomes inoperative, thus leaving the carrier on the shaft s2 at rest in the bath. The shafts s s2 are now at rest with their carriers depressed, and the shaft s3 is rotating and raising its carrier. Vhen the carrier on the shaft s3 is at its highest point, said shaft s3 is stopped by the action of its arm 3 on the collar 2 of the rod frs, the latter heilig thereby moved to remove the clutch ,7' on the countershaft t3 out of engagement with the pulley p and into an inoperative position. The operator then, after the raised carrier on the shaft s3 has been recharged, starts it on its downward course by moving the rod r3, so as to throw the clutch j engaged therewith into engagement with the pulley p', the shaft s3 be#v ing set in rotation. During the rotation,caus ing the downward motion of the carrier on the shaft s, the arm 5 on said shaft strikes the collar 4 on the rod fr', and thereby moves the clutch on the shaft t into engagement with the pulley p, the shaft .5" being thus set in motion and caused to raiseits carrier. Directly after this the shaft s3 is stopped with its carrier in the bath by the action of its arm 3 on the rod r3, moving the clutch on the shaft t3 out of engagement with the pulley p The shaft s continues to rotate until the carrier thereon is raised, and is then automatically stopped by its arm 3 moving the rod yr', and thus throwing the clutch j on the shaft t out of engagement with the pulley p on that shaft, the carrier of the shaft s* being thereby stopped in a raised position so that the machine is in the same condition as at the commencement of the operation. This completes one round of the operation of the machine, the next round being a repetition of the foregoing, and so on.

It will be seen that each carrier is automatically stopped both when raised and when depressed, and that when one carrier is raised the others are depressed. It will also be seen that after the elevation of any carrier the machine is stopped and its operation cannot be resumed until the operator moves one of the clutches to start the raised carrier downwardly, and that the descent of each carrier causes Ithe ascent of the next in the series without action of the attendant. Time is therefore afforded for the unloading and loading of each carrier, and as the carriers always await the action of the attendant when raised and require no further attention until they are again raised, it follows that one operator can conveniently attend to a number of carriers without liability of any carrier descending and immersing the same charge a second time in the bath.

The mechanism is extremely simple as compared with that shown in my patentV above mentioned and can be constructed and operated at much less cost.

The vertical movements of the carriers being caused by the rotation of the cranks, it will be seen that each carrier, when rising from its depressed position, moves slowly at first, while the crank is moving in an approximately-horizontal direction and more rapidly thereafter, the tinned articles being thus caused in rising to break slowly through the surface of the grease-bath and then to rise at a more rapid rate, the object of this varying movement being to prevent the adherence of t-he scum on the surface of the bath to the tinned surface, as described in my later patent, No. 421,599, dated February 18,1890.

It is obvious that the number of carriers and their operating-shafts may be varied, and that two or any desired larger number may be employed. I find it more convenient, however, to employ three, as by the employment of that number a sufficient period of immersion of each carrier in the bath is obtained without liability of a too protracted immersion and the consequent removal of too much of the tin coating by the hot grease.

I do not limit myself to the particular clu tch-and-pulley mechanism here shown and described for reversely rotating the carrieroperating shafts. The clutch -rods t" t2 t3 may be used with any other suitable means adapted to be controlled by said rods to produce the described results.
